Cheerful Volts Mental Institution is a psychiatric hospital in Comedy World. It is Lakeside City's only mental asylum, and it is located near Lakeside Forest. It made its debut appearance in the season 2 episode, Eric for Principal.
Cheerful Volts is a large one-story building. The asylum's orderlies claim to "cater" to the mentally ill residents of Lakeside, when in reality, they always mistreat and berate their patients. The asylum is also notorious for having a spooky nature to it. The fact that it's located right next to Lakeside Forest worsens matters. Faint screaming can usually be heard from the building (mostly at night), and the inside of the asylum is rather dark. Even if there are any functioning lights, they are dimly lit.
- The name of the institution refers to the electric chair.
- The asylum's patients are actually recycled models of various background characters.
